Police said Denver was with his father, older brother, and two others a few blocks away from the Giants’ ballpark when an argument allegedly broke out with some Giants fans.

Both Montgomery’s father and friend have said the 21-year-old acted in self-defense.

“I think anyone who’s getting jumped and had a knife in their pocket would have to … do whatever they could to get out of that situation,” Tatin Davis, Montgomery’s best friend, said. “I know for a fact that I’ve known Mikey for so long that he’s not trying to kill anybody. He was trying to get out of there.”

Reacting to the self-defense claims, Denver’s family has said that he would not have initiated such a fight.
